4 Claims.

This invention relates to spool ejecting and sizing mechanism designedfor incorporation in Winding and for re-winding machines such as arecommonly used in the throwing departments of textile mills, particularlyin winding machines wherein the spools are fioatingly supported anddriven through peripheral contact with continually revolving drivingrotors to draw the yarns or threads from supply packages in the form oflarger spools, cones or skein reels.

In connection with mechanism of the kind referred to, we aim to make itpossible through provision of simple, inexpensive and reliable meanssuch as hereinafter disclosed, to effect automatic displacement of thespools upon becoming fully wound or filled, from contact with thedriving rotors to a retracted idle position where they are supportedagainst further rotation and from whence they can be readily removed bythe machine attendants and quickly re placed with fresh or empty oneswhile the machines keep running.

Other objects and attendant advantages will appear from the followingdetailed description of the attached drawings, wherein Fig. 1 is afragmentary view in front elevation, showing a portion of a winding orredrawing machine conveniently embodying the spool ejecting and sizingmechanism of our invention.

Fig. 2 is a view in sectional elevation taken as indicated by the angledarrows II-II in Fig. 1.

Figs. 3 and 4 are fragmentary views like Fig. .2. showing how themechanism operates to eject and stop the spool at the completion of awindmg.

Fig. 5 is a fragmentary view corresponding to Fig. 1 showing theposition in the machine of a fully wound spool after dofling.

Fig. 6 is a view in side elevation looking as indicated by the angledarrows VIVI in Fig. 5.

Fig. '7 is a view similar to Fig. 5 showing a modification.

With more detailed reference to these illustrations, the numeral 1comprehensively designates the framework of the winding machine whichprovides plural pairs of vertically-spaced open bearing notches such asindicated at 8 and 9 in Fig. 1 adapted to receive the diametricallyreduced ends of spindles like the one shown at III for a spool II. Theyarn Y to be wound upon the spool II is drawn from a supply package I2supported on a shelf I3 at the rear of the machine and enroute to thespool, is diverted over fixed transversely-extending guide rods I4 andI5 for passage between tensioning disks I6 mounted on a stationary railH at the top of the framework I. After emerging from between thetensiOning disks I6 over the guide rod I5, the yarn passes through anotch la in a projection I9 on a traverse 20 which is reciprocatedendwise as required to evenly distribute the yarn along the core of thespool II. The means for actuating the traverse may be of any well knownconstruction and for this reason has been omitted from the drawings. Thespool II is rotated in the direction of the arrow of Fig. 2, throughfrictional gravitational contact of a roller collar 2| on the spoolspindle adjacent one end of the latter with the periphery of a drivewheel 22 affixed to a constantly revolving transverse shaft 23 which isrotative in suitable bearings afforded by the machine framework 1.

The ejecting and sizing mechanism with which the present invention ismore particularly concerned, comprises a cam disk element 26 which ispivoted oif center on a stud 21 on the horizontal arm of an angularbracket 28 (Fig. 2) clamped, with capacity. for both up and down andlateral adjustment, to a pair of stationary rods 29, 30 supportedcrosswise of the machine framework 1. From Fig. 1 it will be noted thatthe cam disk 26 is disposed adjacent the drive end of the spool I I, andthat it has two tread portions 26a and 26b which are eccentric to eachother and to the pivot stud 21, and which are adapted to coactrespectively with the winding on the spool and with the contiguous endhead lid of said spool to effect dofi-lng in a manner presentlyexplained.

Normally during the winding, the disk 26 hangs free on its sustainingstud as shown in Figs. 1 and 2, it treads 26a and 26b free of contactwith the spool head I Ia and the yarn accumulation thereon. Uponaccumulation of the yarn on the spool to a predetermined diameter asexemplified in Fig. 3, it will contact the tread 26a of the disc 26 andas a consequence be rotated clockwise as indicated by the dotted arrowthereon, and eventually, during such rotation thereof, its tread 26bwill be brought into engagement with the periphery of the spool head Ilawhereby, at the end of a, half revolution as in Fig. 4 the spool will beupwardly displaced at one end and take the angular position in which itis shown in Fig. 6 with the roller collar raised out of contact with thedrive wheel and with the corresponding spindle end above the notchbearing 8. Thereupon, by the rotative momentum of the spool I0 andincidental draw of the yarn Y, the lifted end of the spindle II will bepulled inward to rest upon the ledge 3| alongside the notch of 3 bearing8, and there be stopped from further rotation for convenience of readyremoval by the machine attendant and replacement by a fresh or emptyone.

As an alternative and as shown in Fig. 7, a second cam element 26'exactly like the cam element 26 may, if desired, be employed to lifttheother end of the spool II in the same way as above described, withattendant dislodgment of the spindle ends from both of the notchedbearings 8 and 9.

Having thus described our invention, we claim:

1. Spool ejecting and sizing mechanism for a yarn winding or a rewindingmachine wherein the spool is floatingly supported in frictional contactwith a driving rotor, said mechanism comprising a disk eccentricallymounted for free rotation about a fixed axis beneath the spool andhaving two treads in eccentric relation, one for initially contactingthe yarn accumulation on the spool and the other for subsequentlycontacting the periphery of a head on the spool in effecting theejection; and means constructed and arranged to support the spool afterit is filled and displaced for convenience of ready removal from themachine.

2. Spool ejecting and sizing mechanism for a yarn winding or a rewindingmachine in which the spool is floatingly supported in frictional contactwith a driving rotor, said mechanism comprising a. spindle for thespool, an open notched bearing for one end of the spindle, a diskeccentrically mounted for free rotation about a fixed axis and beneaththe spool and provided with two treads'in eccentric relation, one forinitially contacting the yarn accumulation on the spool and the otherfor subsequently contacting the periphery of a head on the spooladjacent the aforesaid spindle end; and a ledge adjacent the notchedbearing for supporting the aforesaid end of' the spindle upondisplacement of the spool by the disk after the spool is filled.

3. Spool ejecting and sizing mechanism for a yarn winding or a rewindingmachine in which the spool is floatingly supported in frictional contactwith a driving rotor, said mechanism com prising a pair of disks eacheccentrically mounted independently for free rotation about fixed axesbeneath the spool and having two treads, one for initially contactingthe yarn accumula-' tion on the spool and the other for subsequentlycontacting the periphery of a head on the spool in effecting thedisplacement; and means constructed and arranged to support the spoolafter.

it is filled and displaced for convenience of ready removal from themachine.

4. Spool ejecting and sizing mechanism for a yarn winding or a rewindingmachine in which the spool is floatingly supported in frictional contactwith a driving rotor, said mechanism comprising a spindle for the spool;open notched bearings for the opposite ends of the spindle; a pair ofdisks eccentrically mounted independently for free rotation about fixedaxes, each having two treads in eccentric relation, one for initiallycontacting the yarn accumulation on the spool and the other forsubsequently contacting a head on the spool; and ledges adjacent theopen bearings by which the spindle ends are received and supported uponfilling and displacement of the spool.
